The latest Canadian case, on the heels of two related deaths in Ontario and Alberta, saw an Oakville, Ontario, man greeted by an angry crowd when he returned to his car in the local Home Depot parking lot. Concerned citizens spotted a child in the man's car, crying and sweating profusely. The father rushed back to his vehicle when he heard an emergency announcement in the store about a child inside a hot car. Upon returning to his car, "he was berated by a group of angry individuals," Halton police said in a release.

The father had reportedly left the child for only 15 minutes, but the temperature inside a car left out in the sun can soar to 50 C in as little as 10 to 20 minutes. Such temperatures can be particularly dangerous for young children.

As we continue to hear stories of children and pets abandoned in hot cars, Canadians are growing increasingly concerned. So we thought we'd ask you: What would you do if you saw a child in a hot car?
